RFID alternatives?

So I want to start a new arduino project and I'm not quite sure how to complete a part of it. This is my idea, I would like to create a push to start button for my car but I have to add some security because I would be removing the keys. I was going to use RFID with a card but I can't get the range I want without spending hundreds of dollars. So I was looking into alternative means and thought about low energy Bluetooth because I will get a range of at least one meter. But I'm not sure what Bluetooth tags could be picked up by what sheild or module or if I have to make my own tags for a receiver. I would like to be able to have a tag on my person and just start my car I don't want to have to pull a tag out and hold it up just to be read.
Please help with ideas or solutions
Thanks in advance and let me know if you have any questions.

Is this the cahallenge for this years final project ?

No I'm sorry it's not. It is a project I have been wanting to do for some time but have been stuck with the distance problem with rfid.

See this thread

An ibeam module is cheap but would give little security.

There are devices desinged for this but they are propriety pairs of tx and rx.

It would be possible to do with arduino but aftermarket solutions are liable to be cheaper.

Two type RFID

  • no Security, encryption and authentication
  • buildin Security, encryption and authentication

iBeacon is same as first type.

Use Active RFID

Active RFID systems typically operate in the ultra-high frequency (UHF) band and offer a range of up to 100 m.

iBeacon Scan/GPS (no Security, encryption and authentication, ~10 m)

Ok thank you so much it's been a big help
